| Abstract: |
| Based on the analysis of the computers practical technology and the
panax artifical drying methods, the computer control system for the panax drying process is studied in this paper,A mathematic pattern of the control object is built up.According to automatic control principle and simulation technology, control algorithms are
developed, the electronic road and program of the control system designed, installed and
tested.This system can trace temperature-time curve with a measurement error less than
0. 25℃, control error less than 0. 5℃ and the measurement temperature scope being 0-100℃. |
